I'm having a problem with email sent from a domain I have hosted by a host company. When I send emails to any us.ibm.com or us.lenovo.com address it comes back as unrouteable. Doesn't matter if I type in the address or just reply to mail sent to me. I can send email to these addresses from hotmail, gmail, AOL, and my work account. I opened a help desk ticket with the hosting company but they told me the domains are not valid, there are notes in the ticket about querying the nameservers and that there is no us.ibm.com mailserver.
However like I mentioned that I can send email to these domains from other email services, and I found the website http://www.dnsreport.com/ and when I put us.ibm.com there it shows around 10 servers that are all working. The emails I have gotten from us.ibm.com addresses all have originating IP addresses that match one of the server IPs listed on the dnsreport website.
I'm not real well versed in issues such as this, and I admit I am a little over my head when it comes to this, but is there any reason I shouldn't be able to send emails to those domains when I can from every other email service I've tried?
